Mt. Gox, once the dominant Bitcoin exchange, accounting for 80% of all BTC trading, was hacked in 2011, resulting in the theft of 850,000 Bitcoin. However, the exchange did not disclose the hack at the time. It wasn't until February 7, 2014, that Mt. Gox filed for bankruptcy, revealing the extent of the losses. The subsequent MtGox leak showed that the exchange had been insolvent for years, with the theft being a major contributing factor. The civil rehabilitation process, which began in 2014, took nearly a decade to resolve, with creditors finally receiving repayment in BTC and BCH worth $9B in 2024. The repayment was a significant development, marking the end of a long and complex process. Mark Karpeles, the CEO of Mt. Gox, was at the center of the controversy, facing criticism for his handling of the situation. The Mt. Gox hack and subsequent bankruptcy served as a wake-up call for the cryptocurrency industry, highlighting the importance of security and transparency. As the industry continues to evolve, the question remains: can we trust exchanges to safeguard our assets?
